What is the main objective of GAGAN satellite?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Provide satellite-based navigation services
GAGAN (GPS Aided GEO Augmented Navigation) is India’s satellite-based augmentation system, built by ISRO and the Airports Authority of India. Ground stations check the GPS signals over the region and send corrections through payloads on geostationary satellites (GSAT-8, GSAT-10 and GSAT-15), so that receivers can fix their position far more accurately and reliably than with GPS alone. Its main user is civil aviation, where it guides aircraft on approach and landing.
